Question

你好我是网页设计新手，我创建一个表单来给出状态代码和状态名称。在PHP中验证这个表单并在另一个文件中完成验证。我不知道如何包含validation.please帮助我验证并在数据库中存储之后。我将附加所有文件，请帮助我的朋友。

function stateAjaxsubmit()
{		
    var statename = document.forms["addstate"]["statename"].value;
    var statecode = document.forms["addstate"]["statecode"].value;
	 
    var valueJson = {
        "State_Code": statecode,
        "State_Name": statename
    };
    
    console.log("Input");
    console.log(valueJson);
	 
     $.ajax(
 	{ 
        dataType: "json",
        cache: false,		    
        contentType: "application/json; charset=utf-8",
 	url : "tocheck.php",
 	type: "POST",
 	data :JSON.stringify(valueJson),
 	success:function(data, textStatus, jqXHR)
 	{
		console.log("Output");
                console.log(data);
 	},
	 error: function(jqXHR, textStatus, errorThrown)
 	{
 	}			 
    });

如果我只是告诉你如何做到这一点，它可能不会帮助太多，你可能最好花一些时间熟悉HTML，PHP和Javascript，看起来你可能是缺少一些关键概念。

现在，我要说忽略javascript部分，只关注服务器上的表单提交和验证。

TL; DR

我建议从这样的视频开始：Build a PHP contact form，它应该涵盖表单提交和错误检查（验证）的一些基础知识。

然后开始研究如何将javascript和PHP结合起来：Submitting a form with AJAX

希望有所帮助！
